Referring to Figure 1 of the drawings, I have used the reference numerall0 to indicate the frame of a truck for supporting my improved device,said frame having at its forward end a housing II in which is included apower unit such as is ordinarily used on trucks and from which isextended a drive shaft l2. The rear end of the said shaft |2 has asprocket wheel l3 carrying a chain M for imparting motion to the shaftI5 which constitutes the main drive shaft of my improved device. Theshaft I5 is rotatably mounted in a sleeve I6, said sleeve being carriedby a suitable bracket I! supported on the rear end of the truck l0. Oneend of the sleeve H5 is fixed to a gear casing l8 (see Figs. 0

ber l9 terminating in an annular frame portion 2| and the member 20having fixed thereto an annular frame member 22.

Rotatably mounted in the members 2| and 22 is a second gear casing 23having an annular portion 24 at its lower end rotatably mounted in themember 22, and an annular portion 25 rotatably mounted in the member 2|.The upper end of the gear casing 23 is provided with laterallyprojecting hub portions 25 and 21, said hub portions having rotatablymounted therein a shaft 28, and thereon a pivotally mounted telescopicframe 29, said frame comprising a fixed section (see Figs. 1 and 2), anintermediate section 3| and an end section 32, said sections eachcomprising parallel side rails and cross members 33. The end section issuperimposed on the intermediate section and the intermediate section onthe fixed section, the side rails of the sections being slidablyconnected by means of a channel member 34 fixed to one of the side railsand a T-bar 35 carried by the adjoining one of said rails, as clearlyillustrated in Figure 14, so that the said sections are free to slideone relative to the other for increasing or decreasing the length of theframe, one end of which is pivotally connected to the truck In by thegear casings I8 and 23, and the hubs 26 and 21 and the sleeve l6, theseconnections providing means whereby the free end of the frame may beswung through various angles relative to the truck body with the freeend extending upwardly or even downwardly if so desired. This pivotalarrangement also permits the frame to be rotated about its longitudinalaxis for the purposes hereinafter more clearly set forth.

For controlling the movement of the said frame 29 about its pivotal endI have provided the following mechanism: Fixed to the bearing member 36of the bracket l! is a gear 31 in mesh with a gear 38 carried by a shaft39 rotatably mounted in the gear casing l8. Fixed to the shaft 39 is aworm gear 40, which is in mesh with a worm 4| carried by a sleeve 42.(See Fig. 9.) The sleeve 42 is rotatably supported on a verticallyarranged shaft 43 supported in the gear casing l8 and in alignment withthe shaft l5. Fixed to the inner end of the shaft I5 is a bevel-gear 44in mesh with a bevel-gear 45 carried by the upper end of the shaft 43and fixed thereto by means of a pin 45. The inner face of the gear 45 isprovided with a clutch element 41 adapted to co-act with the upper endof a clutch element 48 carried by a shift collar 4811 on the upper endof the sleeve 42 and splined thereto by means of a key 49. The gear 44is also in mesh with a bevel-gear 50 rotatably mounted on the saidsleeve 42. The gear 50 has a clutch element 5| adapted to co-act with aclutch element 4817 on the lower end of the shift collar 48a, said shiftcollar 48a having a groove 52 for receiving a shift lever 53 'by meansof which the said element 48 may be elevated or lowered and operativelyconnected with either of the gears 45 or 50, thus providing meanswhereby rotation may be imparted to the worm 4| by means of the sleeve42, which in turn is driven from the bevel-gear 44 by either of thegears 45 or 50, the shaft |5 being driven from the power shaft, all asin the manner heretofore described. A lever 53 provides means wherebythe worm 4| may be rotated in either direction or whereby said worm maybe stopped by moving the shift collar 48a to a neutral position. It willbe seen that if the worm 4| is rotated, then the gear 40 will be rotatedand also the gear 38, by means of the shaft 39, which will cause thegear casing |8 to rotate about the gear 31 or about the center of theshaft I5. This in turn will cause the gear casing 23 to be swung from avertical position, as shown in Figure 8, to a horizontal position, thusproviding means for swinging the upper end of the telescopic framelaterally or transversely of the longitudinal axis of the truck, asviewed in Figure l.

The second frame member 23 may be caused to rotate within the bearingmembers 2| and 22 by the following mechanism:

Fixed about the member 23 near its lower end is a worm gear 54 adaptedto mesh with a worm 55 (see Fig. 8), said Worm being secured to a shaft56 and rotatably mounted in the bearing member 5! carried by the bottomof the gear frame l8. Fixed to the opposite end of the shaft 56 is abevel-gear 58 adapted to mesh with bevelgears 59 and 60, the gears 59and 60 being mounted on the lower end of the, vertical shaft 43, saidgears having their inner faces provided with clutch elements '6! and'62, respectively, (Fig. 7), said clutch elements-being adapted toco-act with the clutch elements formed on the end of a shift collar I5 3which is splined to the shaft 43, said shift collar being actuated by alever 64 carried by a shaft 65 mounted in the gear casing I8, said shaft65 being actuated by a lever -66. Thus, means is provided whereby thegear 58 may be rotated in either direction by the gears 59 and .69 andwherein the worm 55 may also be rotated in either direction and in turncause the second gear casing 23 to be rotated about its vertical axis,as viewed in Figure 8. This movement will cause the telescopic frame torotate about its longitudinal axis when the said frame member is inalignment with the casing 23. The worm gear 54 provides means forlocking the casing 23 in any of its adjusted positions when the shiftcollar 53 is in its neutral or inoperative position.

In like manner, the worm II provides means for locking the frame I8against rotation when the member 48a is in its neutral position.

I will now describe the mechanism for swinging the telescopic frame onthe hub members 25 and 2?: Supported on the lower end of the shaft 43 Ihave provided a sprocket 57 carrying a chain 58 operating on a sprocket69 supported on the lower end of a shaft "I carried by the gear casing23 (see Fig. 10), said shaft 70 having a bevel-gear II in mesh with abevel-gear l2 carried on a shaft 13 supported in the annular bearingmember 25. Rotatably mounted on the shaft it) above the gear II is asleeve I i having splined on its lower end a shift collar I5, having itslower end provided with a clutch element I6 adapted to coact with aclutch element ll in the gear II. Ro-

tatably mounted on the sleeve It is a bevel-gear I8 in mesh with thebevel gear I2, the inner end of the bevel-gear I8 having a clutchelement 19 adapted to co-act. with a clutch element 8% on the upper endof the collar 15, thus providing means whereby power may be transmittedfrom the shaft' Ill to the sleeve M in either direction by simplyshifting the collar F longitudinally of the sleeve "I l.

Fixed to the upper end of the sleeve M is a worm 8I supported to meshwith a worm gear 82 carried by a shaft 83 and in the laterally extendingportion 8 1 on the gear casing 23. Fixed to one end of the shaft '83 isa gear 85 (Fig. 8) in mesh with a gear 85 fixed toa hub 3-? rotatablymounted on the hub 21 and secured to the frame member 29, thus providingmeans whereby, when 8-I, serves to provide means for locking the freeend of the frame in any one of its adjusted -positions.

By this arrangement it will, be seen that the telescopic frame may beadjusted to angular position about a vertical axis and that the end ofthe frame may be lowered to position substantially parallel with theframe Ia! and resting on a suitable support 88 carried by said truckwhen in its folded position, as illustrated in Figure 2, or the framemay be moved to an upwardly iniii) clined position, as illustrated in"Figure -1,,-or to a dotted line position, as illustrated in saidfigure, or to 'a number of desired positions, and the free end of theframe may also be inclined downwardly in order to extinguish fires inbasements, or to any position lower than that occupied by the truck,such as down an embankment.

For shifting the collar I have provided ,the following mechanism: Saidcollar 15 is provided with an annular groove 89 for receiving pins 90carried by a fork in (see Fig. 12'). The said fork 9| is fixed to avertical bar 92 slidably mounted in blocks '93 carried by thegear-casing 23. A bell crank lever 94 is supported within an opening 95formed in the annular member 25 and fixed to the casing 23 by means of apivot member 95, the said bell crank lever 9 having a -horizontallyextending arm 97 which has its free end pivotally connected to the bar92, the said bell crank being provided with a downwardly extending arm98 provided with a link 99 having one end hooked into an annular plateIIIB which is rotatably supported on the casing 23 in such a manner thatas the said plate is rotated, the downwardly extending arm 28 will berocked, causing the free end of the arm 96 to be elevated or lowered,and in turn the bar 92 elevated and lowered and with it the yoke 9i andthe member 15.

For locking the plate I09 in either one of two operative or neutralpositions I have provided a casing I01 fixed to the under side of theplate I B0 and supported therein a slidably mounted lock I52 having itsinner end adapted to enter either one of the openings I03 formed in themember 23. Levers IE4 are pivotally connected to the under side of theplate I69 by means of pivots I85, said levers having their inner endsoperatively connected to the lock I92 and their opposite ends extendingoutwardly through openings we in the casing Ill I, the outer end of saidlevers having keys Ill-I so mounted that as they are pushed inwardly thelevers Iflfl will be rocked and the lock I02 moved outwardly todisengage the opening I53. Pivotally secured to the casing I-lI arelevers I08, by means of pivots I99, having their inner ends alsoconnected to the lock I92, said lock being provided with a spring Ill-9for retaining the end of the look within either one of the openings Hi3.By this arrangement the shift collar I5 may be actuated by "eitherone ofthe levers IM or I98 to release the latch I02, after which the casingMEI and the plate II!!! may be rotated in the manner above described, toactuate the said bell crank 54. Thus, means is provided'for locking themembers I66 and IIlI in any of their adjusted positions.

I will now describe the mechanism for increasing or decreasing thelength of the telescopic frame which is accomplished by power derivedfrom the shaft I 1. Fixed to the upper end of the shaft'lt is abevel-gear Ill? in mesh with a bevel-gear IiI carried by the shaft 28.The bevel-gear I I i is also in mesh with the bevel gear I I2 carried bya shaft I I3 carried in frame members lid, I I5 and H6 (see Figs. 5 and6) the said shaft being provided with a sleeve Illa having a worm I I?supported between the frame members H5 and H5, said worm beingcperatively connected to the shaft I3 by a reversegear device Ilfisimilar to that illustrated in Figure l0 and employing the sleeve I4,and the collar. 5-5 and the gears I2, II and '58, the'shift collar H9being similar to the collar I5 and controlled by a yoke I20 supported ona shaft I2 I which has one end slidably mounted in the frame member H4and the other connected to a lever I22, said lever having the usualspring-actuated pawl I23 to operate in notches I24 in the sector I25,the spring-actuated pawl I23 being controlled by rods I26 carried bylugs I21 supported on the pivoted lever I28. The pawl may be releasedfrom its notch by swinging the upper end of the lever I28 in eitherdirection, thus providing means whereby the pawl may be automaticallyreleased in a manner hereinafter described. By this arrangement it willbe seen that the worm II1 may be rotated in either direction by powerfrom the shaft I I3, the said worm II1 being in mesh with a worm gearI29 carried on a shaft I36 supported in the fixed section of thetelescopic frame, having on its inner end a gear I3I in mesh with asecond gear I32 mounted on a shaft I33 (see Fig. also carried by thestationary section of said frame.

Fixed to the central portion of the shaft I33 is a sprocket I34supported between frame members I35, said frame members havingextensions I36 connected to the frame member H6. Supported between theupper ends and also between the lower ends of the members I35 aresprocket pinions I31 mounted on suitable pivots I38. A chain or otherflexible device I39 has one end provided wtih a hooked rod I 46 mountedin a plate I M fixed to the outer end of the end section 32 of the frame29, said plate I4I projecting downwardly across the outer ends of theintermediate section 3I and the fixed section 36. Said chain E39 ispassed over the upper pinion i31, around the sprocket I34 in a reversemanner, as illustrated in Figure 6, thence around the lower pinion I31,thence over and between pulleys I42 carried by frame members I43supported on a rod E44 carried by the frame member 36, thence over apinion I45 carried by a rod I46 mounted in plates I41 carried by theouter end of the fixed frame member 69. The chain is then passed over apinion I46 carried by a transversely arranged rod I49 supported in thelower ends of bars I56 attached to the inner end of the intermediateframe 3|, thence around a pinion I5I carried by a transversely arrangedshaft I52 carried in the lower ends of plates I53 supported on the outerend of the intermediate section 3!, thence around a pinion I54 carriedby a transversely arranged shaft I55 supported in bars I56 carried bythe inner end of the end section 32, thence to a hooked rod I51 carriedby the plate MI.

The operation to extend the telescopic frame is as follows: Assumingthat the lever I22 has been actuated and the clutch member H9 isoperatively connected with one of the gears H8 and that the worm H1 isrotated in such direction as to rotate the sprocket I34 in acounterclockwise direction, then it will be seen that tension will beapplied to the lower run of the chain I39, causing said lower run tomove towards the left, as viewed in Fig. 6, and then tension to beapplied to the upper run of that portion of the chain travelling overthe pinion I46, which will tend to move the frame member 36. In likemanner, the bar I56 will be moved toward the right, while the upper runof the chain I39 is being extended toward the right, or, in other words,taking up the slack given out by the movements of the members I56 andI56. A reverse movement of the sprocket I34 will tend to draw the framesections together. Thus, means is provided whereby the frame may belengthened or shortened by means of power derived from the main driveshaft I5, said poweroperated mechanism being manually controlled and setinto operation or made to become inoperative by means of the manuallyoperated lever I22. Means is provided whereby the clutch element II9 maybe automatically moved to its neutral position at such time that theframe sections have been moved to their maximum extended positions.

The means for automatically moving said clutch element to its neutralposition will now be described: It will be seen from Fig. 6 that themembers I56 and I56 extend upwardly above the main frame sections, themembers I56 having supported thereon one end of a ladder section I58,the other end of said ladder section being carried by the upper edge ofthe plate MI in such a manner that said ladder section will be moved inunison with the end section 32 of the telescopic frame. The upper endsof the members I 56 support an intermediate ladder section I59 which isslidably mounted on the section $56 by means of guide devices similar tothose illustrated in Fig. 14, and slidably mounted on the section I59 isa fixed ladder section I66, the inner or lower end of the section I66being fixed to uprights I6I carried by the fixed section of saidtelescopic frame. Each of the said ladder sections is provided with theusual transversely arranged rungs I62. Supported beneath the rungs I62of the fixed ladder section I is a tube 663 (see Fig. 4) in which isslidably mounted a rod I64 having fixed to its inner end a bar I65, theinner end of which is pivotally connected to the member I28 of the leverI22. The outer end of the bar I65 is provided with a downwardlyextending portion I66 adapted to travel in a slot I61 in the lower sideof the inner end of the tube I63, the outer end of said tube also beingprovided with a slot I68 for receiving a downwardly extending lug I69 inthe outer end of the rod I64.

Supported beneath the rungs I62 of the ladder section I59 is a tube I16having slidably mounted therein a rod I1I, the inner end of which isprovided with an upwardly extending lug I12 slidably mounted in the slotI13, the upper end of the member I12 being designed to engage thedownwardly extending portion I66 when the ladders are at their innerposition of movement. The outer end of the rod I1I is provided with adownwardly extending portion I 14 extending through a slot I15 in thetube I19 and adapted to engage a fixed cross bar I16 carried by theladder section I58.

When it is desired to extend the frame and ladder sections, the leverI22 is moved to the left, also the collar I I9, setting in motion thesprocket I34, as illustrated in Figs. 4 and 6, at which time the rod I64is moved inwardly. The ladder section I59 will then move outwardly ortowards the right relative to the ladder section I 66, and the sectionI58 will be moved relative to the section I59, which will cause the lugI12 to engage the lug I69 and the lug I14 to engage a cross bar I11carried by the section I 58 at the time the ladders reach their maximumextended positions, which will cause the rod I1I to be moved outwardly,which in turn will cause the rod I64 to be moved outwardly and the upperend of the member I28 of the lever I22 to be rocked to the right, whichwill cause the lefthand rod I26 to be elevated, and with it the pawlI23. The lever I22 will then be moved to the right until the awl I23enters the middle notch I24, at which time the member II9 will beautomatically shifted to its neutral position; If the frame and laddersections are at their extended position of movement and it is desired tomove them to their contracted position, then the lever I22 is shifted tothe right and a reverse movement of the rods I84 and Ill, and the coplar II9 will take place, causing the member I28 to be shifted to theleft, together with the lever I 22', and the shift collar H9 againreturned to its neutral position, thus providing I means whereby theframe and ladder sections may be mechanically operated and at the sametime provide means whereby any accidental breakage will be prevented incase the operator fails to manually control the lever I22 to throw theshift member II9 to its neutral position. The pulleys I42 and the platesI 43 provide means for taking up slack in the chains I39, 26I, 262, 263and 285, each set of plates being pivotally connected to one end of arod I18, one end of said rod being supported in the frame member I19 andpro'-' vided with a spring I88 whereby yieldable tension is provided fortaking up any slack in the chains I39, 26L 2 62, 263, and 255'. I

For supporting and actuating the nozzle supporting arm and the nozzlecarried thereby I have provided the following mechanism: Supportedadjacent to the outer face of the plate I is a housing I8I (see Figs. 6,and 18), one end of the said housing'l 8 I extending laterally beyondone edge of the'plate I4'I a considerable distance. Rotatab1y mounted inthe outer end of said housing is a sleeve I82 having its inner endprovided with a semi-circular flange" I88 (see Fig. 16:), and its outerend provided with a collar I84; the collar being detachably' fixed tothe sleeve by means'of a screw I85. 7

Fixed to one of the section members 32 i a bar I86 extending through oneside of the'casin'g I8I and supporting a sleeve I8? extending outwardlyand terminating at the end of the housing I8I-. Rotatably mounted on thesleeve I81 is a sleeve I88 having supported on its outer end a gearcasing I89 designed to support the nozzle-supporting arm hereinafterdescribed. Fixed; on the inner end of the sleeve I88 is a collarI98adapted to have one end engage the inner end of the collar I84, thusproviding means whereby the sleeve I82 will hold the sleeve I88 inposition on the sleeve I87. However, the casing I89 may be detached fromthe housing I8I by simply slidingthe sleeve I82 outwardly. V

In order to lock the sleeve I82 in position I have provided a rotatablymounted sleeve I9I having a sprocket wheel I92 at one end and asemi-circular lug I93 at its other end (see Fig; 16), this lug I99beingso arranged that one-end is against the inner end of the bar I86,as illus trated in Fig. 18, with the lug I93 engaging the lug I83 whenthe sprocket I92 is in one position of its rotative movement. It will beseen, however, that said sprocket I82 may be rotated to such positionthat the lug I83 will disengage the lug I83, at which time the sleeveI82 maybe withdrawn from the housing I8I, thus providing means fordetaching thecasing I89 from the free end of the telescopic frame. I v

For rotating the casing I89 about anaxis ex tending longitudinallythrough th housing I8I I have provided a sleeve I 9fi rotatably mountedwithin the sleeve E81, having itsouter end ter minating near the casingI89 and provided'with clutch jaws I95, as illustrated in Fig, 17, the

The means for imparting rotation to the shaft 2H] and longitudinalmovement to the link 228, as well as rotation to the casing I89 aboutthe longitudinal axis of the casing I8I, and means for impartingrotation to the sprocket I92 or detaching the casing I89 will now bedescribed: The shaft I33 is provided with a series of pivotally mountedframe members 23I, each of the said frame members comprising sidemembers 232 spaced apart and connected by means of shafts 233, each ofwhich is provided with a sprocket pinion 234 (see Fig. 13) said framesbeing pivotally supported on said shaft I33 to oscillate through alimited arc. A sprocket wheel 235 is mounted between the members 232 andfixed to the shaft I33, so that as the shaft I33 is rotated, all of thesprockets 235 will be rotated therewith and in unison with the sprocketI34. Each of the frame members 23I is provided with an operating member236 pivoted to the frame member 23I at points above the shaft I33,whereby a longitudinal movement of the member 236 will cause the frame23I to be oscillated. Each of the members 236 is screwthreaded to ashaft 231, one end of which extends through suitable bearings in theframe member 233, and has at its end a bevel-gear 239 which is in meshwith bevel-gears 249 and 24I carried by a shaft 242 extendingtransversely of the frame member 29. One end of the shaft 242 isprovided with a spur-gear 243 in mesh with a second spur-gear 244mounted on one end of the shaft 28, the gears 24!! and 24I being looselymounted on the shaft 242 and operatively connected therewith by means ofshift collars 245, whereby the bevel-gears 239 may be operated in eitherdirection. The shift collars 245 are each operated by means of a bellcrank lever 246 pivotally supported on the top edge of the frame member238. Each ofthe bell crank levers 246 has a link 24'! connected to thelower end of a lever 248 pivotally supported to a standard 249, by meansof a pivot 25!], and supported by the frame members 233 and H5, saidlever having a slot 25I for receiving said pin, and a laterallyprojecting pin 252 adapted to operate in a notch 253 in the upper edgeof the sector 254 carried by the upper end of the support 249. The pin252 i yieldably retained within said notch by means of a spring 255 toprovide means whereby the bell crank 246 may be shifted in eitherdirection by elevating the lever 248 so as to lift the pin 252 out ofthe notch 253, after which the lever may be shifted either clock-wise oranticlock-wise with the pin 252 resting on the member 254 to actuate theshift collar 245, each end of which is provided with clutch elements forengaging clutch elements on their respective bevel-gears 249 and MI. Ifthe said shift sleeve has been moved into engagement with one of thebevel-gears 249 or 24I, then the bevel-gear 239 will be rotated, andwith it the screwthreaded shaft 231, which in turn will cause the member236 to be moved longitudinally thereof and the frame 23I rocked. Each ofthe members 236 is provided with an upwardly projecting lug 256 in whicha rod 251 is slidably mounted having'one end provided with an upwardlyprojecting portion 258, said rod also being provided with an angularportion 259 terminating in a horizontal portion 269, the free end ofwhich is connected to the lower end of the lever 248. By thisarrangement it will be seen that if the member 236 is moved to theright, then the lug 256 will engage the member 258 and cause the rod 260to be moved towards the right, which in turn will shift the upper end ofthe lever 258 to the left until the pin 252 is over the notch 253. Thespring 255 will then draw the pin within said notch, locking the shiftcollar 245 in its neutral position. Thus means is provided formechanically operating the frames 23I for the purpose of controlling thenozzle arm-operating devices and for automatically disengaging them whena pre-determined movement has been accomplished.

One of the frames 23I is provided with a chain 263 adapted to pass overthe upper sprocket wheel 234 and around the sprocket wheel I31, aroundthe sprocket wheel 235 in the reverse manner, as shown in Fig. 6, andaround the under sprocket wheel I31 and the sprocket wh'eel 234, thenceover and between the sprocket wheels I42, thence around the sprocketwheels I45, I48, I5I, I54, and the sprocket wheel I99, which is in thehousing I8I, thence to the place of beginning. The chains 26I, 262, 263and 265 are each provided with frames 23I and operated in exactly thesame manner, and for that reason the position of the chain 263 only willbe described in detail. However, each of the last said chains operatesits respective sprocket wheels in the housing I8I (see Fig. 18).

The chain 252 passes over the sprocket 264, which is connected to thesleeve I94, which in turn is connected to the casing I89. It will,therefore. be seen that any rotation of the sprocket 264 will cause saidcasing I89 to be rotated and the nozzle-supporting arm 2I0 to be swungin an are about the axis of said sleeve. Assuming that it is desired toswing the arm 2I0 through a pre-determined arc (less than so as toenable the operator to position the nozzle 239 to a pre-determinedpoint, then the operator grasps the lever 248 to shift the correspondingcollar 245, wherein one of the corresponding bevel-gears 249 or 24I willbe actuated, and with it the corresponding bevel-gear 239, causing thescrew-threaded shaft 231 to be rotated and the member 235 to be actuatedand the frame 23I oscillated. Assuming that the upper end of said frameis moved in an anti-clock-wise direction, as viewed in Fig. 6, causingthe chain to be wrapped around the upper side of the sprocket 235 andunwrapped on the under side in an anticlockwise direction and the upperrun of said chain to be moved to the left, which in turn will cause thesprocket 264 to be also rotated in an anti-clockwise direction, thuscausing the arm 2 I9, as viewed in Fig. 19, to be lowered, a reversemovement of the lever 248 will cause the frame 23I to be oscillated in aclock-wise direction and the chain 262 to be wrapped around the sprocket235 in a clock-wise direction, thus causing the upper run of the chain262 to be moved to the right and the sprocket 264 to be moved in aclock-wise direction. Each of the chains 25I, 262, 233 and 265 isprovided with sprockets I54 mounted on the shaft I55 and the sprocketsI48 mounted on the shaft I49, sprockets I45 mounted on the shaft I46,and sprockets I5I mounted on aaespes 7 the shaft I52, similar to thoseprovided for the chain I99. Any rotation of the shaft I33 and thesprocket I3 3 to lengthen or shorten said frame also causes thesprockets 235 to be rotated and all of the nozzle-operating chains to beactuated in exactly the same manner as provided for in the chain I39. Itshould be borne in mind that both of the free ends of the chain I39 areconnected to the frame member MI and that as the said member I91 ismoved inwardly or outwardly no movement of the ends of said chains ispermitted, one relative to the other or to said frame. In like mannerthe housing I8I may be moved toward or from the frame member 23I bytelescoping the frame 29 without causing any movement of the upper andlower runs of those portions of the chains extending within the housingIBI and over their respective sprockets within said housing, withoutcausing rotation of said sprockets, as long as the frames 23I are heldagainst oscillation. However, rocking the frame 23I will rotate thesprockets within the housing IBI, regardless of whether or not thesprockets I34 and 295 are rotated. Thus, it will be seen that. the arm2H) may be swung about its hori zontal axis by simply actuating thechain 292 by means of the corresponding actuating mechanism, includingthe shaft 242, the bevel-gears 2A9- and 2M, and the shaft 231 controlledby the lever 248 which may be automatically moved to neutral position incase the operator fails to stop the power-operated device at the propertime by means of the shaft 289 and the lugs 259 being engaged by eitherthe member 259 or the shoulder 259 as the frame 23I is moved to itslimit of movement in either direction.

The operation of my device is as follows: Assuming that the telescopicframe is folded in its normal position and resting on the support 83, asshown in Figs. 2 and 3, and it is desired to extinguish a fire developedin the third floor of the building 2 55, the truck I9 may then be movedto position in front of the building, as indicated in Fig. 1, a hose 26!being attached to the nozzle 239. It is further assumed that the shaftI5 is being constantly rotated from the power shaft I2 and the shaft 93is also being rotated by the shaft I5, causing the chain 68 to rotatethe shaft 70. The member I9I may then be grasped and rotated relative tothe member 23 to cause the yoke III to be shifted, and with it thecollar 15, to engage one of the gears II or 18, which will then causethe worm 8| to be actuated and the gear 82 rotated in a clock-wisedirection, as shown in Fig. 10, which in turn will cause the gear 86 tobe operated in an anti-clock-wise direction and the free end of theframe 29 to be elevated to the position shown in Fig. l. The lever I2 2may then be actuated to cause the shift collar H9 to be moved intooperative engagement with the reverse gear mechanism M8 for controllingthe worm II by power derived from the shaft H3. This in turn will causethe shaft I33 to be rotated-by means of the gears I3I and I32, therotation of the shaft I33 causing the sprocket I34 to be rotated in aclock-wise direction, as viewed in Fig. 6, thereby actuating the chainI39 to cause the frame members 3| and 32 to be moved relative to eachother and to the frame member 99, and extended to the positionillustrated in. said Fig. 1. The arm 2I9 will at this. time be restingparallel with the, frame member 31, as illustrated in Fig. 2. The lever248 may be actuated to set in operation the gear mechanism forcontrolling the chain 292 by as cillating the frame member 23I in aclock-wise direction, as viewed in Fig. 6-, causing the arm 2E1! to beswung upwardly in a clock-wise direction and at such an angle'that thesaid arm will enter the window opening 298. The flexible element 2I3will then be in a plane common to the aXis of rotation of said arm.

If it is desired to rotate the said arm 2I0 about its longitudinal axisthrough an angle of 90 to bring the flexible element in a planesubstantially at right angles to the axis of rotation of said arm, tothe position illustrated in Fig. 1, the

, operator will then operatethe control lever 298 corresponding to thechain 293, passing over the sprocket wheel I99 mounted on the sleeveI98, whereby the gear 299 will be rotated and with it the gear 2 and thearm 2H3. In order to direct the stream of water from the nozzle to thecorner 269 of the building 266, the nozzle may then be flexed relativeto the arm 2H1 by operating the control lever 248 corresponding to thechain 26I which passes over the sprocket 206 mounted on the shaft 294,causing said shaft to be rotated and the crank 293 to be actuated, whichin turn will cause the flexible element 2 I3 to be flexed through thelink arrangement 221a and 224 before described, by moving the link 221longitudinally, thus providing means whereby the nozzle 239 may beadjusted to any desired angle and supported to position within thebuilding being burned, if so desired, even in a room which is entirelyfilled with smoke and heated at such temperature that it would beimpossible to be entered by a fireman, and to bring the nozzle so closeto the fire that the water from the hose 26'! may be delivered directlyon that portion of the building being burned, all of the arm-actuatingdevices being controlled by an operator positioned at a point near thepivoted end of the telescopic frame at a position where he will not beaffected by the heat and smoke of the fire. If it should so happen thatthe building should collapse by being burned, and the nozzle or itssupporting arm, or the hose leading to the nozzle, became entangled,broken or burned off, then the casing I89 may be unlocked from thecasing I8! by simply operating the lever 248 corresponding to the chain295 which passes over the sprocket I92, mounted on the sleeve HM, androtation of the sprocket through an angle of 189, will cause the lug I93to disengage the lug I83 so that the casing I99 may be easily andquickly detached and a similar casing with another hose nozzle and itssupporting arm substituted with very little delay. The ladder sectionsprovide means whereby firemen may be conveyed to the point of disasteror to the outer end of the telescopic frame for the purpose of fireescape. The frame 29 may be rotated about its longitudinal axis for thepurpose of bringing the shaft 294 in a vertical position instead of ahorizontal position, if so desired, wherein the arm 2 I9 may be rotatedsubstantially in a horizontal plane instead of a vertical plane, or theentire telescopic frame may be rotated about a vertical axis so that theframe may be inclined at various angles about said vertical axis, or theframe may be tilted about a horizontal axis to place it in variousangles relative to the ground surface. The free end of the frame may bealso brought to position where it may be inclined downwardly from itspivotal point of support I6, if so-desired. At the same time the arm 2III may be swung either in a vertical or a horizontal plane with thetelescopic frame in any of its inclined positions of adjustment, thusproviding means whereby the nozzle 230 may be caused to enter openingsof various heights and positions relative to the truck, and the nozzleadjusted to operate at various angles after the arm 2|!) has beenentered into the building.
